The UNLPam Consultant presented the technical progress report on the Study of the Environmental Flow of the Desaguadero-Salado-Chadileuvu-Curaco River and the environmental damage caused by the cessation of runoff from the river system in the province of La Pampa. The work is coordinated by Pablo Dornes and Jose Gobbi.
Different scenarios of environmental flows were presented based on which the recomposition of the fluvial ecosystem of the Desaguadero-Salado-Chadileuvu-Curaco (DSChC) river in the Pampas territory is possible, which is strongly degraded due to the interruption of fluvial runoff as result of the storage, diversion and unilateral anthropic use of the waters of the main Andean tributaries of the Desaguadero-Salado-Chadileuvu-Curaco river through the construction of dams-reservoirs.
The environmental damage resulting from the null fluvial runoff that affects the Pampas portion of the basin was also presented and evaluated, and that translates into the deterioration of the ecological functions of the fluvial ecosystem, in the loss of its hydric and biological connectivity., in the deterioration of productive activities and in the impoverishment of riverside populations and the impairment of their cultural traits.
The technical group explained in detail, for each of the different environmental flow scenarios, its water quantification and its environmental assessment, in order to provide tools for management and decision-making aimed at recomposing river runoff in the system.
The study is in the final stage of preparation and has great technical and methodological soundness, for which the Provincial Government considers it of great importance and foundation for the development of efforts in the Desaguadero-Salado-Chadileuvu-Curaco basin. .
The presentation was made before the counterpart commission of the provincial government made up of the Secretary of Water Resources, Nestor Lastiri; the state prosecutor, Romina Schmidt; the national deputy, Hernán Perez Araujo; the director of Water Policy of the Secretariat of Water Resources, Gaston Buss; and Alejandrina Aballay from the State Prosecutor’s Office.
